Color image display system and color image pickup system that use decentered optical system

Abstract

A color image display system and a color image pickup system adapted to electronically correct the color shift of color separation images caused by a decentered optical system used to display or capture a color image. The color image display system has an image display apparatus including a color image display device for displaying a color image composed of color separation images superimposed on one another. The displayed color image is projected into an eyeball of an observer through a viewing optical system that is formed from a decentered optical system including a decentered prism having at least a decentered internally reflecting surface with a power, together with an entrance surface and an exit surface, which are transmitting surfaces. The pixel position of each color separation image to be displayed on the color image display device is shifted so as to cancel a color shift of the corresponding color separation image caused by the decentered optical system.
